When it is desired to dispense the contents of the container, the closure cap is unscrewed or removed while the shaker disc 1 remains securely held in place by the interlocking engagement of the beads i6 and 20. The contents of the container may then be dispensed by shaking the container as is indicated in Fig. 3. The shakerv disc may readily be removed when desired for refilling the container, or for other purpose. When the closure cap is placed on the container, the disc 1 makes a hermetic seal between the container neck and cap, thereby protecting the contents of the container.
